v i claims. (ci. 30e-4a) This invention relates .to compound tools andmore particularly ,to b rriclimasons hairliners,` which include a hammerhead yand a blade or bit.

An object of the invention is to provide a brickmasons hammer, with itsVcompound head made up of only two sections, detachably securedtogether,` whereby the blade section may beI removed for grinding,renewal or substitution of another size'or shape of blade.

Another important object is to provide a novel means for detachablysecuring together a harnmer head section and a blade section, with themeans including a portion overlapping both sections, whereby aparticularly .sturdy joint is provided.

Still another object is to provide a doublebevel joint between the twosections of the novel hammer. Withthe joint provided, coupled with themeans for securing the two sections together,

therek is substantially Ano tendency for the tool to fracture at thejoint. y

Other objects and advantages of this invention will be apparentduringthecourse of the following detailed description, taken inconnection with the accompanying drawing, and in which drawing. f l

Figure 1 is a vertical section of the novel compound tool."

Figure2 is a top plan thereof, assembled.

Figure 3 is a top plan of the blade section disassembled. e l

Figure 4 is a top plan of the hammer section, alsodisassambled. l

Figure 5 isa fragmentary bottom plan of the novel tool, with .handleportion in` horizontal section.

In the drawing, wherein for the purpose of illustration is shown apreferred embodiment of the invention and wherein similar referencecharacters designate corresponding parts thruout the several views, theletter A maydesignate the novel compound tool, B the hammer sectionthereof, C a tool, such as the blade section, D A means for detachablysecuring together sections B and C, and E a handle section.

The hammer section B is of one piece, of any approved metal, andincludes a hammer head Ill, which may present a substantially flat,forward, rihe section E has an upper face I2, curved if preferred, abottom face I3 and a stepped beveled portion lei at its end opposite thehead It. Intermediate the head Ii) and portion I4 is a handle-receivingportion I5 preferably provided with a suitable opening I6 to receive oneend of the handle section E.

ylo

.With reference to the stepped beveled portion id, which is of novelconstruction, there-are' pro vided two beveled faces, Vthe upper oneIVI1 lex tendingV downwardly from vthe upper face I 2 and, preferably,inwardly toward the headf lil. `Next, at the base of the face I'Iris ashoulder I8 extending away from the head I8 and providing asubstantially at upper-face i9 Vwith its lower face comprising a portionof thebottom yface I3. Fromthe outer end o f the face I9 kof theshoulder 'i8 extends downwardly and toward the head Il),

second orlower beveled face 2|. Erefenably,

the beveled faces I'I and I?.I parallel yeach other.

Thru the shoulder I8 from its upper face- IS 'to .the face I3 extendsari-opening, such as the per'- foration 22, and into the upper face IN2extends a recess 23, preferably U-shaped, with the curved portion of therecess disposed nearest the-head it. This recess also opens into" thebeveledface y Il, andthe functions, of this perforation and recess willbe later described indet'ail. Y

Now, `as for the tool C, which is shown as a blade or bit section 25,this is of one piece with `an upper face 2,6 when the compound tool A isassembled, merges vinto the face I2, a bottoni face 2l, a sharpened endportion28 and a stepped beveled end portion 29 cppositelthe'portion 28.`

. With reference to the stepped beveled portion 29, this is of novelconstruction, and presents two beveled faces, theupper beveled face3ilextending downwardly `from the upper face 26"a`nd, preferably, awayfrom the endportion 29. B'- low the base of the face 3 6, is a flattenedface 3l' extending `toward the end portion and "at its inward end is thesecond beveled face 3 3 which extends downwardly and, preferably', awayfrom the end portion 29, paralleling the face SIT.

Into the upper face 26 extends a recess 34, preferably U-shaped with thecurved portion of the recess disposed nearest the end portion 28. Thisrecess Sil also opens into the beveled face d. At thevbottom of therecess 34 is a perfora tion 35 extending to the attened face 3|, all fora purposenow to `be described. y

Means D for detachably coupling or connecting the sections B and Ctogether preferably includes a bolt having a special head 40, oval in bein intimate face-to-face contact when the sections B and C are placedtogether, as in Figures 1 and 2, as are likewise the beveled faces 2Iand 33. In addition, the flattened face 3l is adapted to be inface-to-face contact with the flat upper face I9 of the shoulder I8.When so assembled, the perforations 22 and 35 align and the two recesses23 and 34 form a single recess, oval in shape, as shown in Figure 2,which is adapted t snugly accomodate the head 4I). Being of this shape,the bolt will not turn when the head is in the last-named recess and thenut 42 may be readily tightened or loosened.

It will be noted in Figure 1 that this head 4B overlaps portions of boththe sections B and C and this novel assembly provides a particularlystrong construction, coupled with the steppedbeveled face-to-facecontact of the sections B and C. The head 40 due to its elongation is sosocketed in the sections B and C as to prevent turning thereofincidental to removal or tightening of the nut.

'Being readily disconnected, the section C, which may take variousshapes as to its end portion 28, may be replaced by a bit or blade ofdifferent free end, or the tool C removed in order to be drawn out orresharpened. It is also apparent that a workman need carry but onehammer section B, with handle E, and selected kinds of tools C, insteadof a multiplicity of brickmasons hammers with various styled bitspermanently attached thereto.

'Ihe handle section E is, of course, conventional and is shown asextending into the opening I6 at one end but, insofar as the novelty inthis invention is concerned, could be integral with the section B.

Various changes may be made to the shape, size and arrangement of partswithout departing from the spirit of the invention or the scope of thefollowing claims.

I claim:

1. In a brickmasons hammer, a hammer section, a blade section and meansdetachably securing said sections together, including a bolt with theshank thereof extending thru said sections and the head thereofoverlapping and in intimate contact with both of said sections.

2.
